ADAMTSs (A Disintegrin And Metalloproteinase with ThromboSpondin motifs) are secreted proteases dependent on Zn2+/Ca2+, involved in physiological and pathological processes and are part of the extracellular matrix (ECM). Here, we investigated if ADAMTS-1 is required for invasion and migration of cells and the possible mechanism involved. In order to test ADAMTS-1's role in ovarian cancer cells (CHO, NIH-OVCAR-3 and ES2) and NIH-3 T3 fibroblasts, we modified the levels of ADAMTS-1 and compared those to parental. Cells exposed to ADAMTS-1-enriched medium exhibited a decline in cell migration and invasion when compared to controls with or without a functional metalloproteinase domain. The opposite was observed in cells when ADAMTS-1 was deleted via the CRISPR/Cas9 approach. The decline in ADAMTS-1 levels enhanced the phosphorylated form of Src and FAK. We also evaluated the activities of cellular Rho GTPases from cell lysates using the GLISA® kit. The Cdc42-GTP signal was significantly increased in the CRISPR ADAMTS-1 ES-2 cells. By a Förster resonance energy transfer (FRET) biosensor for Cdc42 activity in ES-2 cells we demonstrated that Cdc42 activity was strongly polarized at the leading edge of migrating cells with ADAMTS-1 deletion, compared to the wild type cells. As conclusion, ADAMTS-1 inhibits proliferation, polarization and migration.
